3522HBFRV-5023-3A - Roper - 3" Roper with Triple Lip Seal / Carbon Bearings - LJI Part: 3522HBFRV-5023

• Offering the same high degree of sealing reliability as a mechanical seal, triple lip seals are better suited for viscous products that tend to set up while the pump is idle. Mechanical seal faces tend to stick together with high viscosity liquids, such as resins, glues and paints.
• The lips create an effective barrier to product leakage, and will move freely upon resumption of pumping a thickening substance. In cases where extreme circumstances can cause catastrophic failure of mechanical seals, the resilient nature of the triple lip seal makes it relatively immune to sudden failure.
